+title: What firewall ports should I open to use NetBird?
+sidebar_position: 1
+---
+### Incoming ports
+NetBird's agent doesn't require any incoming port to be open; It negotiates the connection with the support of the signal and relay services.
+### Outgoing ports
+NetBird usually won't need open ports, but sometimes you or your IT team needs to secure and verify 
+all outgoing traffic, and that may affect how NetBird clients connect to the [control layer](/overview/architecture) 
+and negotiate the peer-to-peer connections.
+
+Below is the list of NetBird hosted endpoints and ports they listen to:
+* Management service: 
+  * **Endpoint**: api.wiretrustee.com
+  * **Port**: TCP/443
+* Signal service:
+    * **Endpoint**: signal2.wiretrustee.com
+    * **Port**: TCP/443
+* Relay (TURN) service:
+    * **Endpoint**: turn.netbird.io
+    * **Port range**: UDP/5555-65535
